hi i did see it, i'm a bit hesistant to give you advice since my PB is less than yours. You don't seem like your hardstuck given by the graph. Seems like more time needed. My top score is 3333 which after PBing all of mattyow DCC playlist KovaaKsWinningChestnutPot
To me your reactivity and smoothness are the same level so it's just both skills need to be improved. You even know the bot profiles already so it's just skill
You can also try Dotonbot's reactive, KovaaKsClearingPickedBrush
I'll see if I can beat your score tonight then post what I did to get there if i do
